No. 476,312 1 Claim. (Cl. 28222) The present invention relates to articles for making carbon copies of markings made on an original sheet.

As is well known, when making carbon copies on a typewriter, for example, it is necessary to carefully arrange a sheet of carbon paper between the original sheet and the copy sheet so as to transfer the markings made on the original sheet to the copy sheet. This operation involves not only initial careful alignment of the set of sheets but maintaining the sheets in proper alignment while they are introduced into the typewriter. In addition, the fingers of the operator often become smudged with carbon, and the care required in proper positioning of the carbon paper between the original sheet and the copy sheet represents a delay resulting in an undesirable increase in the costs of operation.

It is a primary object of the present invention to provide an article which will avoid the above drawbacks.

More particularly, it is an object of the invention to provide an article which will enable a carbon copy to be made without requiring the operator to interleave and position a sheet of carbon paper between the original and the copy sheet.

The objects of the present invention include the provision of an article which will automatically situate the sheet of carbon paper and a second copy sheet in proper relationship with respect to each other after the sheet of carbon paper has made a copy of a given original sheet on a first copy sheet which, after having received the markings transferred by the carbon paper, is removed from its position with respect to the sheet of carbon paper.

In addition, it is an object of the present invention to provide an article of this type which is extremely convenient to handle, particularly with respect to eliminating any difiiculty in connection with the grasping of a selected sheet of copy paper preparatory to removing the selected sheet of copy paper from the article.

Furthermore, it is an object of the present invention to provide an article of the above type which is extremely inexpensive, so that the cost of the article of this invention is far less than the present conventional costs involved in the time required for the operator to properly position sheets with respect to each other.

In its more basic aspects, the article of the present invention includes a sheet of carbon paper having an upper exposed face against which an original sheet is adapted to be placed. This sheet of carbon paper has, opposed to its upper exposed face, an impression-transferring face adapted to transfer a carbon copy of the markings made on the original sheet. Situated one behind the other, next to the impression-transferring face of the sheet of carbon paper, are a plurality of copy sheets, the uppermost one of which is situated directly under the sheet of carbon paper and the remainder of the copy sheets united in a group and located behind the initially used copy sheet. After the markings have been placed on the original sheet so that the latter is removed from its position with respect to the sheet of carbon paper, the copy sheet be tween the sheet of carbon paper and the second copy sheet is removed so as to leave the second copy sheet in position to receive a carbon copy of the next original sheet which is placed over the same sheet of carbon paper. Preferably the copy sheets are detachably connected with the carbon sheet so that after each copy sheet is completed, it can be detached from the article to leave, in a in the art,

The invention is illustrated by way of example in the accompanying drawings which form part of the application, and in which:

FIG. 1 is a perspective illustration of a pad composed a plurality of the articles of the present invention. FIG. 2 is a front elevation of one possible embodiment of an article according to the present invention, shown on an elarged scale as compared to FIG. 1, and having parts broken away so as to illustrate in a clearer manner the structure of the invention.

FIG. 3 is a transverse section taken along line 3-3 of FIG. 2 in the direction of the arrows.

Referring now to the drawings, there is shown in FIG. 2 an article 10 according to the present invention. These articles 10 are combined together in such a way that a plurality of these articles form a pad 12, as shown in FIG. 1.

The article 10 includes an upper sheet 14 of carbon paper having an exposed upper face visible in FIG. 2 and against which an original sheet is adapted to be placed. The face of the sheet 14 which is not visible in FIG. 2 carries the coating of impressiomtransferring material so that whatever markings are made on the original sheet will be transferred to a copy sheet situated next to that face of the sheet 14 which is opposed to the upper exposed face thereof visible in FIGS. 1 and 2. As may be seen from FIG. 2, situated next tothe sheet of carbon paper 14 is a sheet of copy paper 16, while situated next to the sheet of copy paper 16 is a second sheet of copy paper 18. In the particular example illustrated, there are three additional copy sheets 20, 22, and 24, so that in the particular example illustrated a set of five copy sheets are situated one behind the other next to the sheet of carbon paper 14. Thus it will be noted that the first copy sheet 16 is situated between the second copy'sheet 18 and the sheet of carbon paper 14.

As is apparent from FIG. 3, the several sheets are fastened together by a suitable binding 26 well known and situated along the upper edges of all of the sheets. In this way, all of the sheets of the article 10 are connected to each other to form a unitary article. However, it is preferred to provide an arrangement where, when a transfer of a carbon copy to the first sheet 16 has been completed, the copy sheet 16 can be easily detached, and for this purpose the several sheets are respectively provided with tear lines formed by lines of perforations 26, 28, 30, and 32. These lines of perforations are situated adjacent the upper edges of the several sheets 16, 18, 20 and 22, respectively. The final sheet 24 requires no line of perforations since, after a carbon copy is placed on the final sheet 24, the carbon sheet 14 can simply be removed at the upper edge where it is joined by the layer of adhesive 26' or the like to the sheet 24, and after removal this sheet of carbon paper 14 can be used in the manner of an ordinary sheet of carbon paper. Therefore, as a result of the lines of perforations, the several sheets between the carbon paper sheet 14 and the final sheet 24 are respectively detachable from the remainder of the sheets.

According to a further feature of the invention, all of the sheets which have a line of perforations are of the same dimension from the line of perforations to the free bottom edge of the sheet. Thus, the distance from the line of perforations 26 of the sheet 16 to the free bottom edge 36 of the sheet 16 is precisely the same as the distance from the line of perforations 28 of the sheet 18 to the free bottom edge 38 of the sheet 18, and, of course, the sheets 20 and 22 also have the same length from their lines of perforations 30 and 32, respectively, to their free bottom edges 40 and 44. As a result of this feature, the free bottom edges 36, 38, 40, and 44 are offset with respect to each other so that the operator can easily grasp the edge 36 of the sheet 16, for example, in preparation for detaching the sheet 16 from the remainer of the article along the line 26. Of course, these lines of perforations 26, 28, 30 and 32 are also offset in the same way as the free bottom edges of the several sheets so as to maintain the same length dimension for the several copy sheets.

Thus, in using the article of the invention, the operator will simply place against the upper exposed surface of the sheet of carbon paper 14 an original sheet which may have at its upper end the letterhead of the particular company or other organization using the article of the invention. The bottom edge of the original sheet can be aligned with the bottom edge 36 of the sheet 16, and in this way the top edge of the original sheet will be aligned with the line of perforations 26, so that proper alignment of the carbon copy material on the sheet 16 will be guaranteed.

With the original sheet arranged in this way with respect to the article 10 of the invention, typing is carried on in the usual manner with the entire article 10 passing through the typewriter together with the original sheet. Of course, markings can be made through devices other than typewriters, but the structure of the invention is designed particularly for use with a typewriter.

When the sheet 16 has received its carbon copy from the original sheet, the original sheet is, of course, removed together with the article 10 from the typewriter and the original sheet is placed in an envelope to be mailed to whomever the original sheet is addressed. The operator will then grasp the free edge 36 of the sheet 16 and detach it, along the line perforations 26, from the article 10 so that the sheet 16 may now be filed away to form a carbon copy of the original letter. As soon as the sheet 16 is detached in this Way the sheet 18 is automatically properly positioned with respect to the sheet of carbon paper 14 so that when the next letter is typed, the operator need only place the original sheet against the sheet of carbon paper 14 and the sheet 18 will be properly positioned with respect to the sheet 14 to receive a proper carbon copy in the manner described above. In this way, copies of successive original sheets can be provided through the same sheet of carbon paper 14 to the successive copy sheets which, one after the other, become properly situated next to the sheet of carbon paper to receive the next copy therefrom. i

Thus, the article of the invention completely eliminates the necessity of properly positioning the carbon sheet between the original sheet and the copy sheet each time a carbon copy is to be made.

To form the pad 23 of FIG. 1, the layer of binding material 26' is extended to form the binding indicated in FIG. 1, and with this adhesive type of binding material the articles 10 can be separately detached from the pad 12 at the upper layer of adhesive 26' thereof, so that after all of the copy sheets of one article 10 have been used, the operator can detach the next article 10 from the pad 12 to repeat the above operations therewith.

Although the present invention has been described in some detail by way of illustration and example for purposes of clarity of understanding, it is understood that certain changes and modifications may be made within the spirit of the invention and scope of the appended claim.

What is claimed is:

A tablet comprising a plurality of copy paper sheets all of different lengths with the uppermost being the longest and the other copy paper sheets being successively shorter, a carbon sheet as the uppermost sheet of the tablet, said carbon sheet being of a shorter length than each of said copy paper sheets, said uppermost carbon sheet being the exact length as the lowermost copy paper sheet, a layer of binding material overlying and embracing said carbon sheet and each of said copy paper sheets at the uppermost edges thereof and defining a flush edge for said tablet, all said sheets being bound together by said layer of binding material at the upper end of said tablet and having their lower ends shingled, each of said paper sheets except the lowermost being perforated adjacent said layer of binding material at a uniform distance from said lower edge of said copy paper sheets and defining a series of copy paper sheets all of Which have the same dimension when detached from said tablet.
